Abstract
The utility model discloses a film blowing machine head, comprising a mold core and a machine head body; a material inlet is arranged at the bottom end of the mold core, a material outlet is arranged on the outer circumstantial wall of the mold core, and the material outlet is communicated with the material inlet; the machine head body is sheathed on the mold core, the cavity of the inner part of the machine head body is adaptive to the shape of the mold core, and a material extruding gap is arranged between the machine head body and the mold core; at least four material outlets of the mold core are uniformly arranged at the periphery of the mold core; the material outlets are uniformly arranged at the periphery of the mold core, so as to lead the material to be rapidly and radially dispersed and to be axially blended, thereby leading the material before being compressed and formed to be fully blended and greatly improving the forming quality of the product.
Description
Technical field
The utility model relates to a kind of inflation film manufacturing machine, relates in particular to the head of using on a kind of inflation film manufacturing machine.
Background technology
Existing inflation film manufacturing machine head comprises core rod and the handpiece body that is set in the core rod outside, is provided with top clearance between core rod and the handpiece body, the material of fusion enters between the top clearance from core rod, through mixing radially, axially pull out middle air blowing film forming from film outlet port.The Flow of Goods and Materials that allows that is provided with on the core rod is three or four to the discharging opening of top clearance, the material of fusion speed when radially merging is slow like this, what material was shaped is not mixed before fully, and the pressure when making extruding is inhomogeneous, greatly reduces the quality of product.
The utility model content
Technical problem to be solved in the utility model provides that a kind of mixing of materials is abundant, the uniform inflation film manufacturing machine head of pressure.
For solving the problems of the technologies described above, the technical solution of the utility model is: the inflation film manufacturing machine head comprises: core rod, and the bottom of described core rod is provided with charging aperture, and described core rod periphery wall is provided with discharging opening, described discharging opening and described feeding inlet; Handpiece body, described handpiece body are set on the described core rod, and the cavity of described handpiece body inside and the shape of described core rod are suitable, are provided with the material extrusion gap between described handpiece body and the described core rod; At least six of the discharging openings of described core rod, and the circumferential periphery that evenly is arranged on described core rod.
As a kind of improvement, described core rod comprises the core rod body, and described core rod body is fixedly connected with a mouthful mould, and described core rod body is provided with helical groove, and the discharging opening of described core rod is communicated with the starting end of described helical groove.
As further improvement, described mouth mould comprises changeover portion and profiled section according to the direction of Flow of Goods and Materials, and the length ratio of described changeover portion and profiled section is 3: 1.
As further improvement, described handpiece body is provided with the die orifice ring, and described die orifice ring and described mouthful of mould are suitable.
Owing to adopted technique scheme, the inflation film manufacturing machine head comprises: core rod, and the bottom of described core rod is provided with charging aperture, and described core rod periphery wall is provided with discharging opening, described discharging opening and described feeding inlet; Handpiece body, described handpiece body are set on the described core rod, and the cavity of described handpiece body inside and the shape of described core rod are suitable, are provided with the material extrusion gap between described handpiece body and the described core rod; At least six of the discharging openings of described core rod, and the circumferential periphery that evenly is arranged on described core rod; The even periphery that all is arranged on core rod of a plurality of discharging openings can allow material carry out radially dispersion fast, carries out axial fusion again, and material is mixed before compression molding fully, and the pressure when making extruding is even, has improved the quality of product greatly.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, the inflation film manufacturing machine head comprises:
Core rod 1, described core rod comprises core rod body 2, described core rod body 2 is provided with helical groove 21, the bottom of described core rod body 2 is provided with axial charging aperture 22, even equal six discharging openings 23 that are provided with radially on described core rod body 2 periphery walls, described each discharging opening 23 all communicates with charging aperture 22, and described discharging opening 23 is communicated with the starting end of described helical groove 21, general discharging opening 23 correspondences a helical groove 21, can certainly one discharging opening 23 at interval corresponding helical grooves 21, the increase of discharging opening 23 can allow material carry out radially dispersion fast, carry out axial fusion again, material mixing and axial transporting radially also quickened in the setting of helical groove 21, and material is mixed before compression molding fully, improved the quality of product shaping greatly.The upper end of described core rod body 2 is fixedly connected with mouthful mould 3, described mouth mould 3 comprises the linkage section 31 that is connected with described core rod body 1 according to the direction of Flow of Goods and Materials, changeover portion 32 and profiled section 33 that certain gradient is arranged, the length ratio of described changeover portion 32 and described mouthful of mould 3 is 3: 1, the lengthening of changeover portion 32 can allow the slow transition of material, can improve the quality of product like this.
The course of work of the present utility model is:
Melt material is come in from the charging aperture 22 of core rod body 2 by extruder, discharging opening 23 on core rod body 2 perisporiums comes out, enter helical groove 21, the material of fusion carries out fusion radially along with helical groove 21 and overflows, enter in the material extrusion gap 5 between core rod body 2 and the handpiece body 4, finally leave helical groove 21, become the gap between axial bead mould 3 and the die orifice ring 6 to extrude, come out middle air blowing film forming from the film outlet port drawing.
